Also what voltage and amperage rating is the push button? I would like to use either a factory defrost switch or an illuminated power button from a desktop computer.
Thanks in advance to everyone! I have been searching for this for about a year now!

Did you ever get a reply to this? I'm going to be adding this to my '96 Volvo 850. I would like to have an LED readout to indicate what "position" the circuit is activating. I would prefer an led readout like the newer Prius; 1st press Red (ACC on), 2nd press amber, 3rd press green.Success!!! It works perfectly. Im wondering one more thing. Is there a way I can add a little daughter board to this so that I can control the led in the switch Im using? What I was thinking would be to make something so that the single light would flash slow when it is in ACC, faster in IGN and after start was pressed it stays on solid. I have the circuits already to make an led flash so thats not a problem its switching between them that Im trying to figure out. I figured I may need to use another decade counter and just diode the led outputs to a single pin on the clock pin of the decade counter. woth that done I can trigger two flasher circuits on Q0,Q1 and just straight out on Q3. This may work it may not but it sounds logical. If you got an idea on how I can do this my setup will be complete. Thanks so much Soren for this I am forever in your debt
